Abstract (en)
[origin: CA3164686A1] The invention relates to a device (10, 10') for measuring a change in length (?L) having a first fastening element (11, 11'), a second fastening element (12, 12') and at least one length element (15), which is arranged between the two fastening elements (11, 11', 12, 12') and has a first end (15a), a second end (15b) and a length (L) along a longitudinal direction (R), wherein a force (F) acting parallel to the longitudinal direction (R) leads to a change in length (?L) of the length element (15), wherein a lever element (20) having a first end (20a), a second end (20b) and a fulcrum (D) is arranged transversely to the longitudinal direction (R), wherein the lever element (20) comprises a first lever arm (21) with a first length (a) between the fulcrum (D) and a first lever arm end (21a) and a second lever arm (22) with a second length (b) between the fulcrum (D) and a second lever arm end (22b). The second length (b) is greater than the first length (a) and the length element (15) is arranged with its first end (15a) pivotably on the first lever arm end (21a) of the first lever arm (21) and the second lever arm end (22b) of the second lever arm (22) is connected to a mass body (30), the movement of which can be detected by a scanning element (40).
